Description
Technical field
The present invention relates to rope sensor truing tool and application method, belong to gathering pipe fields of measurement.
Background technology
Pipeline it has been covered with ship everywhere, design, making and inspection after installation etc. one in board of these pipe fittings are
The operation of row is referred to as " pipe laying ".Usual ship is sectional construction, is accomplished by segment folding time-division intersegmental pipeline
Gathering pipe can not produce miscellaneous gathering pipe to connect by pipeline designs drawing, and the making of gathering pipe is generally adopted
Take type method and site welding connection.Both approaches have the following disadvantages：(1) precision is not high, the defective work that can have 5%
(2) activity duration is long, and in transport operation, contingency is multiple, and there is potential safety hazard (3) needs the backmans such as flange and angle bar
Tool, cause the operations such as welding in waste of material (4) ship, cutting exist disaster hidden-trouble (5) need to be skilled in technique, it is veteran specially
Industry skilled worker could be completed in pipeline makes the most it is difficult to " ensureing the good precision of finished product ".But use both above side
Often the gathering pipe flange bolt hole malposition produced often still occurs using both above method in method, causes
Situation about can not install.
Patent zl201110323558.x provides a kind of spherical coordinate measuring machine measured for gathering pipe, and the device can
With the quickly accurately locus of two flanges to be closed up of measurement, and be processed into gathering pipe making drawing, in shipbuilding industry
Large-scale application is obtained.The linear measure longimetry device of the gathering pipe measuring machine is a rope sensor, rope sensor
Measuring principle is that the encoder one inside drawstring drives changes, and passes through the cooperation of internal circuit and supporting machinery structure, coding
Certain rule can be showed between the signal intensity of device and the length change of drawstring, in use, by certain circuit and
Algorithm, reads out the signal intensity of encoder, you can to calculate pulling rope length change.But in rope sensor manufacturing process
In can have a certain error, usually 0.5 ‰, i.e., per error of meter 0.5mm, when measure length than it is larger when, this error
It can linearly rise, the corresponding relation of encoder code value and pulling rope length is changed, be calculated by original corresponding relation
Pulling rope length and reality pulling rope length between there is larger error, finally influence measurement result, cause measurement accuracy to be deteriorated,
On the other hand, easily cause drawstring during measurement process medium pulling rope is put back in continuous pull-out to reverse, drawstring, which is reversed, also can
Precision to pulling rope length is impacted, and finally influences measurement accuracy.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, the present invention provides a kind of rope sensor amendment work
Tool and application method, the instrument small volume are lightweight, and data can be corrected at any time, can be daily as cell measurement apparatus is closed up
The instrument of adjustment in accuracy.
Technical scheme：To achieve the above object, a kind of rope sensor truing tool of the invention, including base and bearing
Frame, the bearing and base are connected by connecting rod, and the base is provided with two through holes be arrangeding in parallel, respectively first through hole
With the second through hole, vertical rod is inserted into first through hole, and the second through hole is provided with the crossed beam trunking parallel with the second through-bore axis, the axle
Bolster includes great circle loop-drive, and parallel boss is extended with the indentation, there of great circle loop-drive, axle is provided with boss, pacifies on axle
Equipped with bearing, great circle loop-drive is stuck in vertical rod.
Preferably, the bottom surface of the base is plane, the plane is vertical with the axis of first through hole.
Preferably, the bearing be arranged in parallel with crossed beam trunking.
A kind of application method of above-mentioned rope sensor truing tool, comprises the following steps：
(1) each parts of rope sensor truing tool are installed, base bottom is measured using survey tool and put down
Face and the distance of bearing centre, it is L to remember this length；
(2) plane of base is close to the end face of fag end；
(3) drawstring is pulled out, and hook is hung on bearing；
(4) the encoder output valve M of rope sensor is detected；
(5) pulling rope length L and encoder code value M are input in PDA10, software corrects pulling rope length L and coding automatically
Device code value M corresponding relation.
In the present invention, above-mentioned base is stainless steel, and the second through hole is arranged at bottom, there is crossed beam trunking sideways, and top has the
One circular hole, vertical rod is a stainless steel round bar, and one end is arranged in the circular hole of base, and the other end installs bearing bracket stand, and bearing bracket stand is not
There is square groove rust steel matter, one end, and the other end has a circular hole, and the other end of vertical rod is mounted in the circular hole, and bearing is mounted in square groove
In, axle is filled within the bearing, and on bearing bracket stand.Above-mentioned base end face is flat, and being one has high light cleanliness and position
Circular hole in the plane of degree of putting requirement, the plane and base is vertical.Bearing bracket stand adjusts the position of bearing bracket stand afterwards after installing, make axle
Hold parallel with the crossed beam trunking of base, the two line is parallel with vertical rod.The bottom portion of groove plane and bearing of base are measured after regulation
The distance at center, this distance is accurately measured using conventional slide measure, and by this size marking to base, it is L to remember this size.
During amendment, base is close on the rope stretching head plane of spherical coordinates measuring machine, drawstring is pulled out, through the crossed beam trunking of base, and
Hook is hung on bearing, the code value M of now encoder is read by PDA, it is above-mentioned length L that now code value M is corresponding, and
And be accurate corresponding, code value M and length L are input in PDA, PDA Survey Softwares are that can correct encoder code value automatically
